Hm? The relays are not online -- we kicked them in mid June.

We don't know of any relays right now that are attacking users.

Or said another way, if anybody knows of relays that are doing any attacks
on Tor users, ssl stripping or otherwise, please report them. I believe
that we are up to date and have responded to all reports.

That said, there is definitely the uncertainty of "I wonder if those
OVH relays are attacking users -- they are run by people I don't know,
though there is no evidence that they are." We learned from this case
that making people list and answer an email address didn't slow them down.

I still think that long term the answer is that we need to shift the
Tor network toward a group of relay operators that know each other --
transparency, community, relationships, all of those things that are
costly to do but also costly to attack:

https://lists.torproject.org/pipermail/tor-relays/2020-July/018669.html

But the short term answer is that nobody to my knowledge has shown us
any current relays that are doing attacks.

Hope that helps,
